What are some of the limitations of Medicare data I need to consider?
• The exclusion of persons under age 65 who are neither disabled nor have ESRD (End-Stage Renal Disease) • The exclusion of individuals over 65 not enrolled in Medicare • Exclusion of claims paid by a source other than fee-for-service Medicare (e.g., managed care organizations or HMOs) • Data (variables) were collected for the purpose of making healthcare payments, not for research top
